How to switch from CallTrackingMetrics (CTM) to CallTracker
Switching from CallTrackingMetrics (CTM) to CallTracker means new tracking numbers, because numbers cannot be ported in. You run both tools side by side while the new numbers take over: the website and online listings can move the same day with US or Canadian numbers (about 6 business days for the first number in most other countries, because of the regulatory review), and printed placements move when you replace them.
Before you decide
CallTrackingMetrics, now CTM, is a US call tracking and contact-centre platform, from $79 per month billed monthly.
Stay with CallTrackingMetrics (CTM) if: You run a contact centre and want call tracking in the same platform. You need an API that writes data, or HIPAA compliance listed by the vendor. You want to port your existing numbers into your call tracking tool.
What moves and what does not
| What | How it moves |
|---|---|
| Tracking numbers | New numbers. CallTracker cannot port numbers in, so you order a new number per placement and keep your CallTrackingMetrics (CTM) numbers active until calls to them stop. |
| Placements and campaigns | Recreated by hand: one placement per ad, listing, sign or traffic source, each with its own number. There is no importer. |
| Website number swapping | Replace the CallTrackingMetrics (CTM) script with the CallTracker dynamic number insertion snippet. Do not run both swapping scripts on the same page. |
| Call history and recordings | Not imported. Export them from CallTrackingMetrics (CTM) before your access ends; CallTracker starts recording history from your first tracked call. |
| CRM logging | Reconnect in Settings → CRM: HubSpot, Salesforce and Pipedrive log each call on the matching record, and new callers create one. |
| Google Ads call conversions | Connect Google Ads with your Google login in Settings → Conversion tracking (available once Google approves CallTracker's API access) and choose the conversion action calls should count toward. |
| GA4 and Meta call conversions | Enter your GA4 Measurement ID and API secret, or your Meta dataset ID and Conversions API token, in Settings → Conversion tracking. |
Step by step
Step 1 · Day 0
Check your contract and export your data
CTM offers monthly, annual and 2-year pre-pay billing. If you pre-paid, plan the switch for the end of the pre-paid period. Export call logs and any recordings you want to keep from CallTrackingMetrics (CTM).
Step 2 · Day 0, a few minutes
Create your CallTracker account
Sign up with a business email, subscribe to CallTracker Pro and top up prepaid credits for numbers and minutes.
Step 3 · Seconds in the US and Canada; about 6 business days for the first number elsewhere
Order tracking numbers
US and Canadian numbers are provisioned instantly. Most other countries need a regulatory bundle (business registration and proof of address): CallTracker checks it, then Twilio reviews it — Twilio states "The review process generally takes up to three business days, but in some regions it might take several weeks." Submit the bundle as soon as your account exists, so the review runs while you prepare the rest.
Step 4 · As soon as the numbers are live
Switch your website and online listings
Install the CallTracker snippet in place of the old one, then update the numbers on Google Business Profile, directories and online ads.
Step 5 · Same day
Reconnect integrations
Connect your CRM, Slack or Microsoft Teams alerts, webhooks or Zapier, and Google Ads offline conversions.
Step 6 · On your normal print and media cycle
Replace printed and broadcast numbers
Billboards, vehicle wraps, flyers and radio spots keep the CallTrackingMetrics (CTM) number until you replace them. Keep those numbers active in CallTrackingMetrics (CTM) until they no longer ring.
Step 7 · When the old numbers go quiet and your term ends
Cancel CallTrackingMetrics (CTM)
Check the last weeks of call logs on both tools first so no live placement still points to an old number.
What the regulatory step looks like
Outside the US and Canada, the New Placement form asks for an approved regulatory bundle before a number can be issued. Every step, who does it and its stated time are listed in how long it takes to get a tracking number.
